Directions (Q. 1 – 5): What value should come in place of question mark (?) in the following questions?

1. √16384 ÷ 4 × 16 =? - 18312 ÷ 12 + 142

1678

1842

1426

2154

None of these

Explanation:

Answer: b)

√16384 ÷ 4 × 16 = x – 18312 ÷ 12 + 142

(128/4)*16 = x – (18312/12) + 196

512 = x – 1526 + 196

X = 512 + 1526 – 196 = 1842

Explanation:

Answer: b)

√16384 ÷ 4 × 16 = x – 18312 ÷ 12 + 142

(128/4)*16 = x – (18312/12) + 196

512 = x – 1526 + 196

X = 512 + 1526 – 196 = 1842

Question 2 of 10

Directions (Q. 1 – 5): What value should come in place of question mark (?) in the following questions?

2. (7/9) of 4068 + 77 % of 1200 = (?)2 – (128 ÷ 16)

64

62

58

56

None of these

Explanation:

Answer: a)

(7/9)*4068 + (77/100)*1200 = x2 – (128/16)

3164 + 924 + 8 = x2

X2 = 4096

X = 64

Explanation:

Answer: a)

(7/9)*4068 + (77/100)*1200 = x2 – (128/16)

3164 + 924 + 8 = x2

X2 = 4096

X = 64

Question 3 of 10

Directions (Q. 1 – 5): What value should come in place of question mark (?) in the following questions?

3. (8 × 8)5 ÷ (512 ÷ 8)2 × (8 × 64)3 = (8)? + 5

12

8

6

10

None of these

Explanation:

Answer: d)

(82)5 ÷ (512/8)2 × (8 × 82)3 = (8)x + 5

810 ÷ (64)2 × (83)3 = (8)x + 5

810 ÷ 84 × 89 = (8)x + 5

810 – 4 + 9 = 8x + 5

815 = 8x + 5

15 = x + 5

X = 10

Explanation:

Answer: d)

(82)5 ÷ (512/8)2 × (8 × 82)3 = (8)x + 5

810 ÷ (64)2 × (83)3 = (8)x + 5

810 ÷ 84 × 89 = (8)x + 5

810 – 4 + 9 = 8x + 5

815 = 8x + 5

15 = x + 5

X = 10

Question 4 of 10

4. ? % of (75 × 4 – 150) = 420 + 752

4280

4520

4030

5060

None of these

Explanation:

Answer: c)

x % of (75 × 4 – 150) = 420 + 752

(x/100)*(300 – 150) = 420 + 5625

(x/100)*150 = 6045

3x/2 = 6045

X = 6045*(2/3) = 4030

Explanation:

Answer: c)

x % of (75 × 4 – 150) = 420 + 752

(x/100)*(300 – 150) = 420 + 5625

(x/100)*150 = 6045

3x/2 = 6045

X = 6045*(2/3) = 4030

Answers :

Direction (1-5) :

1) Answer: b)

√16384 ÷ 4 × 16 = x – 18312 ÷ 12 + 142

(128/4)*16 = x – (18312/12) + 196

512 = x – 1526 + 196

X = 512 + 1526 – 196 = 1842

2) Answer: a)

(7/9)*4068 + (77/100)*1200 = x2 – (128/16)

3164 + 924 + 8 = x2

X2 = 4096

X = 64

3) Answer: d)

(82)5 ÷ (512/8)2 × (8 × 82)3 = (8)x + 5

810 ÷ (64)2 × (83)3 = (8)x + 5

810 ÷ 84 × 89 = (8)x + 5

810 – 4 + 9 = 8x + 5

815 = 8x + 5

15 = x + 5

X = 10

4) Answer: c)

x % of (75 × 4 – 150) = 420 + 752

(x/100)*(300 – 150) = 420 + 5625

(x/100)*150 = 6045

3x/2 = 6045

X = 6045*(2/3) = 4030

5) Answer: a)

(7/84)*(12/156)*4680 = 45 – x

30 = 45 – x

X = 45 – 30 = 15
